Pushing Daisies creator Bryan Fuller’s two-year journey to get his Munsters reboot Mockingbird Lane on air is over. The writer, who developed the project, tweeted to fans that NBC has officially decided not to move forward.

“I tweet with a heavy heart,” Fuller wrote Thursday. “NBC not moving forward with #MockingbirdLane. From producers and cast, thank you all for enthusiasm and support.”

I tweet with a heavy heart. NBC not moving forward with #MockingbirdLane. From producers and cast, thank you all for enthusiasm and support.

As Deadline notes, this officially ends the project, which began during the 2010-2011 development cycle for NBC. It was one of the few in-development projects Bob Greenblatt kept alive when he took over in January 2011. After delays pushed the project back, casting finally got off the ground and a pilot was produced for the current TV season, with X-Men director Bryan Singer directing. The cast included Portia Di Rossi, Jerry O’Connell and Eddie Izzard.

By September, the pilot was completed, but NBC passed on it, despite the reported $10 million investment in it. Eventually, the pilot was aired as a Halloween special and garnered 5.4 million viewers and a 1.5 18-49 rating, which was actually pretty decent for a Friday program. Still, it wasn’t good enough and the network and Fuller made it official this week. Mockingbird Lane will not go forward.

Fuller fans shouldn’t be too disappointed, though. He still has Hannibal at NBC, which will air in 2013. Mads Mikkelsen will play the title character in the series.
